The clip captures the coach approaching a sea of Reds supporters holding flares before bottles and cans are thrown at the windows from every direction.

Passengers are forced to move seats away from a smashed window, as one voice is heard saying: "They are f****** scumbags. I hope the world is seeing this. It is the s******* city in England".

Liverpool have been charged by UEFA following the attack, which damaged the bus so badly it was unable to escort the Citizens players home following their 3-0 Champions League quarter-final defeat.

As can be seen in the video, the bus was showered in beer and smashed repeatedly with bottles and cans as it made its way through red smoke.

Liverpool issued an apology to Manchester City following the incident, which left two police officers injured, saying they: "Condemn in the strongest possible terms the scenes."

It added: "We apologise unreservedly to Pep Guardiola, his players, staff and officials caught up in the incident. The behaviour of a number of individuals was completely unacceptable and the club will co-operate fully with the authorities to identify those responsible."

UEFA opened disciplinary proceedings on Thursday, and charged the Merseyside club with acts of damage and crowd disturbances.

The governing body has also charged Liverpool after fireworks were set off and objects were thrown inside Anfield during the first leg tie.

Manchester City are set to raise serious concerns about Merseyside Police's failure to prevent the incident, after they highlighted the possibility of an attack on their bus two weeks before the match.

The club are also alarmed that Merseyside Police changed the coach's approach to the ground on the day, before advertising its new route.

Greater Manchester Police are now working hard to ensure that there won't be similar scenes next Tuesday when Liverpool visit the Etihad for the second leg. There are fears some supporters may attempt reprisals on Liverpool's team bus.
